R. Wilhelmance at the cathode of a bright green spot, which detaches itself from the cathode and moves towards the anode with a velocity of the order of 10. cm/sec. In we proposed an explanation of this phenomenon and performed some tentative calculations which confirmed the plausibility and self-consiste

Bernhard Danckelmann of Fren kel, Wannier and the Pohl group in the 1930s, a large number of experimental and theoretical studies have been made. Due to these investigations the exciton is now a well-established concept and the electronic structure has been clarified in great detail. The next subjects for investigatio

Bernhard Danckelmannly periodic field of a rigid crystal, but the real crystal lattice is deformable and vibrating. The lattice vibrations cause a spatially and temporally fluctuating potential for the exciton. The . fluctuation gives rise to scattering and momentary localization of the exciton, as reflected in the bro

In modern solid-state physics too, spectroscopy has been one of the principal tools to investigate the complicated system of many elect
